IPC resources are operating system resources, such as message queues, shared memory, and semaphores. When an application server shuts down properly all IPC resources used are removed from the system. In some cases, however, an application server may fail to shut down properly and stray IPC resources may remain on the system. When this happens, it may not be possible to reboot the application server.

The command to remove IPC resources, tmipcrm, resides in TUXDIR/bin. This command reads the binary configuration file (TUXCONFIG), and attaches to the bulletin board using the information in this file.
